We were checking if `backgroundSize` was present on the video element, not the style property of the video element. That meant the IE fallback was being used on all platforms and breaks aspect-ratio preserving poster scaling for those browsers that support it.
TextTracks are queried during player initialization whether they're present or not so the method must be present on Player objects. Make sure the method name isn't minified so it's possible to create a Player object without having to extend videojs.Player directly.
Use string literals to lookup fullscreen-related methods on the player object in the fullscreenToggle component. Otherwise, closure compiler replaces them with minified method names and makes it impossible to supply a simpler "player" object with customized fullscreen logic for the fullscreenToggle to interact with.
When poster() is called with a URL, fire a `posterchange` event to update the PosterImage source and update the video element attribute.
Trigger posterchange after updating the tech
Wait until the tech has updated its poster image before alerting components so they don't see the intermediate state in event handlers. Remove unused variable from PosterImage.createEl.
Don't create new img elements each time the poster is set on ie8
Create the img fallback for the poster during PosterImage initialization on ie8 so we can avoid having to check and possibly create it each time the src is set. Add a test to ensure that new elements are not appended to the poster component when the img fallback is in use and the src attribute is modified.
fixing a broken IE8 test, and adding a negative test, for poster switching.
modified the poster-switching test to accomodate IE8
added a negative test for an undefined poster
fixed the assertion message in the 'undefined' image case
fixed test breakage in Firefox and IE10 (quotes were not being handled properly in the test data)
testing:
ran the tests at the command line, and in Chrome, Firefox, IE8, IE10, Firefox and Safari
all passed
